1. Open up profits, eliminate product under the gas
Lettuce taste fresh and slightly bitter, can stimulate the secretion of digestive enzymes, increase appetite. Its milky serum enhances the secretion of gastric juices, digestive glands, and bile secretion, thereby promoting the function of various digestive organs. It is particularly beneficial to patients with weakened digestive function, decreased acidity in the digestive tract, and constipation.
2. Diuretic milk
The potassium content of lettuce is much higher than that of sodium, which is beneficial to the balance of water and electrolyte in the body and promotes the secretion of urine and milk. People with hypertension, edema, and heart disease have a certain therapeutic effect.
3. Strong body, anti-cancer anti-cancer
Lettuce contains a variety of vitamins and minerals, has a role in regulating the function of the nervous system, and its contained organic content is rich in the body can absorb iron, is very beneficial to patients with iron deficiency anemia. The hot water extract of lettuce has a high inhibitory effect on certain cancer cells, so it can also be used to prevent cancer and cancer.
4. Wide bowel pass
Lettuce contains a large amount of plant cellulose, can promote peristalsis of the intestine, facilitate the digestive tract, help excretion of the stool, can be used to treat various constipation.

4, lettuce cold, postpartum woman Shen Shen.
Does the solar PTZ Camera System Kits work well
In fact, there are no network and no electricity cameras, but they have certain limitations. The working time of a camera with batteries or external solar panels is limited.Monitoring without network means that mobile phones and cameras can only be seen within a certain range of 5~10 meters.
Therefore, no network and no power is just a gimmick. We must pay attention to distinguish when buying.
Is the Solar Camera easy to use
Jiajie intelligent surveillance camera is very good
Advantages and disadvantages of solar monitoring
Probably.
Generally, offline display has the following two conditions.
One is that the installed 4G card has no traffic and cannot provide network connection for monitoring;
The other is that there is a problem with the signal receiving device, which makes it unable to connect to the network. Therefore, the user can access the APP connected to the monitor to check whether there is still traffic on the 4G card. If there is still traffic, there is a problem with the monitoring; If there is no traffic, the renewal fee can continue to be used.
Which is the best solar Outdoor Camera
It may be that the poor contact of the power plug causes power on, heating and power failure, or it may be that the camera's internal control motherboard fails, causing power on for several minutes and automatic power off protection.
The camera works continuously, and the internal chip may overheat, which also exists in many SLR cameras. Some cameras impose time limits on continuous shooting. Centralized power supply with high-power switching power supply
Disadvantages of camera solar power supply
The main advantages of solar photovoltaic power generation are:
(1) Simple structure, small and light volume;
(2) Easy to install, easy to transport, short construction period, and short time to obtain energy;
(3) It is easy to use and maintain, and can work normally in the temperature range of - 50 ℃~- 65 ℃;
(4) Safe, reliable, noiseless, pollution-free, and absolutely clean (pollution-free);
(5) The advantages of building roofs can be used without the restriction of resource distribution regions; For example, areas without electricity and areas with complex terrain;
(6) The rate of price reduction is fast, and the time for energy repayment may be shortened;
(7) It can be matched with the battery to form an independent power supply, or it can be connected to the grid for power generation.
(8) Local power generation and supply without fuel consumption and transmission lines
The main disadvantages of solar photovoltaic power generation are:
(1) Low solar energy density and large coverage area;
(2) Photovoltaic power generation is intermittent and random;
(3) Solar energy resources in various regions are not available, so photovoltaic power generation is highly regional.
